Application of Fuzzy Mathematics for Assessment of Water Quality

With the development of urbanization and the improvement of the people's living standards, the contradiction against water supply and water demand is becoming more and more serious. And the development of the economy led to serious pollution of water, so it is essential to understand the water quality. This paper discussed the choice of the evaluated factors, the operations of the weight value, and compares with the status of the water quality in course of the evaluation. The conclusions indicated that the result of the fuzzy mathematics evaluation represented the water quality of surface waters. The evaluation result was compared with that of the traditional method and the reported results. It is indicated that the performance of the proposed model is practically feasible in the application of water quality assessment and its application is simple.
